Comparison was adjusted for whether respondent was assessed at pretest and posttest or was new in position at posttest, respondent phenotypic index, total number of students enrolled in school, percent of students in Free or Reduced Price Meals program, and percent of White not Hispanic students at school. Sample size is slightly reduced when covariates are added in the models.
